Superior: a novel repetitive DNA element dispersed in the rye genome.

25 Oct 2009 A new class of rye-specific repetitive DNA elements designated Superior has been identified. The rye genome library was constructed by cleavage with EcoO109I, the recognition sites of which consisted of 5'-PuGGNCCPy-3' multi-sequences and were ... Read more...

Chemical constituents from the leaves of Ilex paraguariensis inhibit human neutrophil elastase.

24 Sep 2009 Human neutrophil elastase (HNE), a serine protease with broad target specificity, is the only enzyme responsible for the degradation of elastin which is an insoluble elastic fibrous protein in animal connective tissue. Biologically, elastase ... Read more...

Structure elucidation and complete NMR spectral assignments of new furostanol glycosides from Solanum torvum.

30 Aug 2009 Two new furostanol glycosides, torvosides O (1) and P (2), were isolated from leaves of Solanum torvum. Their structures were completely and unambiguously assigned by one- and two-dimensional NMR techniques ((1)H NMR, (13)C NMR, TOCSY, HSQC, ROESY ... Read more...
